PRETREATMENT OF CATALYTIC DEWAXING FEEDSTOCKS |
| 摘要 |
Catalytically dewaxed lubricating base stock oils that have improved resistance to oxidation are produced by pretreating the waxy furfural raffinate with a zeolite sorbent prior to dewaxing with a zeolite catalyst such as ZSM-5, and conducting the dewaxing at a reduced temperature not to exceed about 675 DEG -700 DEG F. |
